Hello!
I wrote a program that runs fine in version 4. When I tried it in
version 3 I saw different results. I traced the problem to
the function Root. It seems that V.3 Root does not necessarily
order real roots in increasing order.
Example:
Table[Root[2 + 12#1 - 14#1^3 &, n], {n, 3}] // N
gives
{1., -0.827327, -0.172673}
SetOptions[Root, ExactRootIsolation -> True] does not seem to
affect the result.
